LLVM v6.0.0

This is a breaking release, which the major change being a switch from explicit ctx arguments to various API calls, to a global task-bound context that's implicitly set by the Context constructor and removed by the dispose(::Context) function. Practically, this means that you can get rid of all context arguments, and things should generally still work. For more complex uses, see the changes in #358.

Other breaking changes include the rename of called_value to called_operand for consistency with upstream LLVM, and the removal of deprecations from the previous breaking release.

LLVM v5.0.0

This is a breaking release, with as major breaking change the introduction of additional type arguments to many IRBuilder methods that involve pointers. This is to prepare for opaque pointers, and when using a sufficiently recent version of LLVM/Julia, LLVM.jl fully supports running with opaque pointers enabled. Practically, you need to update many call sites (like call! or gep!) to now include the element type of pointers, where this would previously had been deduced from the pointer value. Deprecations are put in place, which will be removed in the next breaking release.

As part of this breaking change, we also changed llvmtype to value_type, in addition to newly introduced function_type and return_type queries.
